NASA launching JPSS-1 weather satellite

NASA launching JPSS-1 weather satellite

The launch is planned for Wednesday, Nov. 15, from Space Launch Complex-2 at Vandenberg Air Force Base, California. Sensors aboard the spacecraft will collect measurements of air, ocean, and ground conditions, as well as fire locations, temperatures and water vapor throughout the atmosphere.

JPSS-1, which will be known as NOAA-20 when it reaches polar orbit, will join the Suomi National Polar-orbiting Partnership (Suomi NPP), a joint NOAA-NASA weather satellite, giving the US the benefit of two, sophisticated polar satellites in the same orbit.

In its orbit, the satellite will pass over the equator about 14 times per day, and cover the globe twice every 24 hours.

For years, policy makers and scientists anxious about a looming polar-orbiting satellite gap that could come once one satellite blinked out from old age, prior to the next one launching. JPSS-1 is the newest and most advanced weather satellite to date using numerous same instruments on the Suomi NPP satellite launched on October 28, 2011. After it successfully clears the on-orbit test phase, NOAA-20 will become the nation's primary polar weather satellite and Suomi NPP will become its back up.

The five instrument suites on JPSS-1 are the Ozone Mapping and Profiler Suite (OMPS), Advanced Technology Microwave Sounder (ATMS), Cross-track Infrared Sounder (CrIS), Visible Infrared Imaging Radiometer Suite (VIIRS), and Clouds and the Earth's Radiant Energy System (CERES). Instruments aboard polar-orbiting satellites, like ones aboard JPSS-1 and its preceding spacecraft, known as the Suomi-NPP, obtain data on the winds and moisture in the upper atmosphere.

Ardern said she raised the issue with Turnbull in passing, but they have not discussed it further. Ms Ardern said it was faster to organise the logistics of any deal with Australia.

Operating in polar orbit, the satellite is created to make global observations that will improve forecasts of severe weather three to seven days out. This interagency effort (JPSS) is the latest generation of USA polar-orbiting, non-geosynchronous environmental satellites.

After billions of dollars in cost overruns and delays, NASA is planning to launch one of the most important weather satellites ever early Tuesday morning.

"The launch of JPSS-1 continues the strong, decades-long partnership between NOAA and NASA in developing state-of-the-art Earth observation satellites", said Sandra Smalley, director of NASA's Joint Agency Satellite Division. Instruments on board were designed by Ball, along with Raytheon, Harris and Northrop Grumman.

Suomi NPP and JPSS-1 will have the same orbit, with JPSS-1 following Suomi NPP by about 50 minutes.

The event is for credentialed reporters only.
